The Many Colors of Iron Oxides
Iron oxides many colors have given cosmetic products their wide range of palette and color selection. According to the list of FDA-approved cosmetic pigments, iron oxide's are famous as Pigment Black 11, Pigment Brown 6, Pigment Brown 7 and Pigment Red 101. Being the primary inorganic makeup coloring ingredient, these oxides are both used in its natural and synthetic state. But to optimize the benefits and aesthetic glow that it brings, natural forms of these oxides are now more popularly used among mineral makeup, offering safe and unique color collections that can perfect any possible look that makeup can create. It even gives mineral makeup the ability to complete a flawless look while bringing in significant benefits to the skin. Hypoallergenic and FDA approved grade of these oxides is used in manufacturing mineral makeup, making them safe for use on sensitive skin types.
For a long time, iron formulations are used in manufacturing virtually all colored cosmetic and beauty products. The history of its cosmetic and aesthetic applications can be traced back to ancient centuries, used in various religious ceremonies of different world cultures. However, it is only by 1900 that iron was manufactured as an ingredient of cosmetic products. Foundations, eye shadow, powder mineral pigments, lipstick, mascara, lip gloss, SPF products, facial powder, blush and pencil and liquid eye liners are just few of the products that use iron oxides as their primary coloring ingredient.
As a colorant, the compound imparts color and opacity that slides easily to the skin. It simple creates a pearl essence out of the makeup job done by makeup artists. Its non-toxic, moisture resistant and non-bleeding properties make it a favorite ingredient of big cosmetic companies. However, with the advent of mineral makeup, there has been an increased demand for iron and its oxides in their natural form. This is inline with mineral makeup’s reputation for using natural-based, hypoallergenic and safe ingredients. There are actually three color classifications achieved by iron oxides as a natural and inorganic pigment:
1. Yellow iron oxide, FeO(OH) is also known as Ferric Oxide Hydrate
2. Red iron oxide, FeO3 – Ferric Oxide or Colcothar is famous for its red color. It is typically water and oil dispersible.
3. Black iron oxide, Fe3O4 is known as ferric ferrous oxide or simply black.
4. Shades of brown is achieved with the addition of Titanium Dioxide.
Mineral makeup use iron oxides primarily as coloring agents. By means of water processing, the natural salts of the compound are oxidized to remove the heavy metal compositions that usually causes skin irritations. As a result, iron oxides in mineral makeup produces unique palette of earthy colors, which are great in foundations and any other makeup products.
